Book excerpt: The last fifty years have witnessed a remarkable renaissance in Q studies with scholars probing every aspect of the Q hypothesis from the existence and extent of Q to the reconstruction of the original text and the place of the document in the history of early Christianity. The time seems ripe for a major commentary on Q to consolidate and extend the discussion of this important document that Matthew and Luke incorporated into their gospels. Q: A Reconstruction and Commentary contains an argued reconstruction of the original Greek text of Q and a commentary on the reconstructed text along with an introduction that explores all of the main questions that swirl around the Q hypothesis.
